AI Generated Solution

To find the heat of formation of 1 mole of carbon monoxide (CO), we can use the given combustion reactions of carbon and carbon monoxide. The heat of formation of a compound is defined as the heat change when 1 mole of the compound is formed from its elements in their standard states. ### Step-by-Step Solution: 1. **Write the combustion reactions**: - The combustion of carbon: \[ C(s) + O_2(g) \rightarrow CO_2(g) \quad \Delta H = -394 \, \text{kJ/mol} ...
